KEY: S = Estimate does not meet publication standards because of high sampling variability or poor response quality. - = Zero or Less than half the unit shown; thus, it has been rounded to zero. X = Not applicable or comparison data unavailable.
1 Ton-miles estimates are based on
estimated distances traveled along a modeled transportation network.
2 Coefficient of Variation.
3 "Truck" as a single mode includes shipment that were made by
only private truck, only for-hire truck, or a combination of private and
for-hire truck.
4 Estimates for pipeline exclude shipments of crude petroleum.
5 In this table, the 2002 and 2007 "Other multiple modes"
categories are not directly comparable due to a definition change. For 2002,
"Other multiple modes" includes shipments using "Truck and
water", "Rail and water", and other mode combinations not
specifically listed. For 2007, "Truck and water" and "Rail and
water" are not part of "Other multiple modes".
NOTES: Value-of-shipment estimates have not been adjusted for price changes. Estimated measures of sampling variability for each estimate known as coefficients of variation (CV) are also provided in these tables. More information on sampling error, confidentiality protection, nonsampling error, sample design, and definitions may be found at http://www.bts.gov/cfs.
